KULTURÁLIS ÖNAZONOSSÁG, TÖRTÉNETI TRAUMA ÉS SZEMÉLYES ÉLETTÖRTÉNET KÖZÉP-EURÓPAI EMIGRÁNSOK ÖNÉLETRAJZAIBAN
No full textA tanulmány a huszadik századi történelmi traumák önéletrajzi művekben való megjelenítését vizsgálja. Érdeklődése a széles vizsgálati anyagot kínáló témának egy sajátos részterületére irányul, mégpedig a történelmi, politikai okok miatt szülőföldjüket elhagyni kényszerülő szerzők autobiográfiáit elemzi. Ezeknek a műveknek a különlegessége nem csupán a történelmi trauma irodalmi feldolgozásának poétikájában rejlik, hanem a kultúraközi identitás több nézőpontú vizsgálatában. Z. Varga Zoltán írása a problematikát a Magyarországot kilencéves korában elhagyó, később az Egyesült Államokban jelentős akadémiai karriert befutó Susan Rubin Suleiman Budapest Diary című művében vizsgálja. A szülőföldjére felnőttként visszatérő szerző műve nemcsak a múlt eltemetésének kollektív történelmi traumákhoz kötődő okait kutatja, hanem az identitás regionális összetevőinek, a kelet-közép európaiságnak kulturális másságként való feltárását is megkísérli. A saját és az idegen együttes nézőpontja a személyes élettörténetre, a szülőkhöz és a gyermekkorhoz való viszony megértésére is kihat, így a múlt elbeszélt identitásként való újraírása több színtéren is zajlik.</jats:p
Identification and characterization of a PDGF-like peptide amongst bovine oviduct secretions
No full textModels of Applied Population Dynamics
No full textThe paper is an overview of our recent results achieved with different coauthors, concerning several research lines of applied population dynamics we initiated some years ago, and mostly published in 2010.First, based on the classic Leslie population model, a dynamic demographic model including controlled immigration iis recalled, and applying the Perron Frobenius theory of nonnegative matrices, a convergent optimal control algorithm is given, in order to address the sustainability problem of the considered payg pension system. Then, concerning the monitoring problem of particular population systems, observer design for certain trophic chains i presented. Furthermore, considering a fish population with a reserve area, we deal with the problem ofsteering the population into a desired new equilibrium, applying a time-dependent fishing effort as a control function. to this end, an optimal control problem is set up, wich is numerically solved using an optimal control toolbox developed for MatLab. Finally, for the analysis of the efficency of certain agents to be applied in biological pest control, corresponding mathematical models are presented that describe the dynamics of the interaction between predator, parasitoid and pest insect populations
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Quasilinear molecule par excellence, SrCl2: structure from high-temperature gas-phase electron diffraction and quantum-chemical calculations - computed structures of SrCl2· Argon complexes
No full textThe molecular geometry of strontium dichloride has been determined by high-temperature electron diffraction (ED) and computational techniques. The computation at the MP2 level of theory yields a shallow bending potential with a barrier of about 0.1 kcal mol−1 at the linear configuration. The experimentally determined thermal average Sr[BOND]Cl bond length, rg, is 2.625±0.010 Å and the bond angle, ∢a, is 142.4±4.0°. There is excellent agreement between the equilibrium bond lengths estimated from the experimental data, 2.607±0.013 Å, and computed at different levels of theory and basis sets, 2.605±0.006 Å. Based on anharmonic analyses of the symmetric and asymmetric stretching as well as the bending motions of the molecule, we estimated the thermal average structure from the computation for the temperature of the ED experiment. In order to emulate the effect of the matrix environment on the measured vibrational frequencies, a series of complexes with argon atoms, SrCl2⋅Arn (n=1–7), with different geometrical arrangements were calculated. The complexes with six or seven argon atoms approximate the interaction best and the computed frequencies of these molecules are closer to the experimental ones than those computed for the free SrCl2 molecule
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
